Title: Improvements relating to means for heating and cooling seated enclosures
IPC: B61D27/00
Filed: 1934-06-20
Abstract: 440,109. Ventilating vehicles or other seated enclosures. COMPAGNIE BELGE DES FREINS WESTINGHOUSE, 97 Avenue Louise, Brussels. June 20, 1934, Nos. 18250 and 18251. Convention dates, June 21, 1933 and Dec. 27, 1933. [Class 137] Seated enclosures such as vehicles are supplied with hot or cold air through openings in the seats either at ground level or at the top of the seat backs. Two seat units 1 located back to back enclose an air chamber divided into two portions 2<a>, 2<b> ; fresh air is admitted to one portion, say 2<a>, and issues through holes 8<a> in the back and through holes 5<a> beneath the seats. Vitiated air is withdrawn from the other portion 2b through similar holes. All the lower openings 5<a> can be used for distributing hot air, and all the upper openings for cold air. It is preferable to supply cold air through the openings 5b, 9 directed towards the gangway, and in this case the vitiated air is withdrawn through compartment 2<a>. In a modification, the air supply to below but seats may be controlled by a valve located below each seat. In Fig. 7 a heat-exchanger 31 is provided, a fan 30 supplying vitiated air from an inlet 24 in the roof and a fan 27 supplying fresh air through a heater 28 to ports 19 below the seats 2. Alternatively a cooler may be used in the conduit 29 and the directions of the air currents reversed.

Patent GB-716312-A (GB)
Title: Improvements in or relating to the handling of coded pulse trains
IPC: H04L25/06
Filed: 1950-07-21
Abstract: 716,312. Digital electric calculating apparatus. SOC. D'ELECTRONIQUE ET D'AUTOMATISME. July 21, 1950 [July 25, 1949No. 18287/50. Class 106 (1). [Also in Group XL(c)] Fig. 3 shows a carry-over operator of an electrical computer in which a number is represented by a pulse series of predetermined amplitude and repetition frequency. The input pulses are applied at 16 to the tapping 14 of the delay line 11 which is shorted at 13 and terminated in its characteristic impedance at 12, the position of the tappings being such that if a pulse as shown at 18 is applied at the input tap a curbed pulse as at 19 is produced at the output tap 15, the positive component of which is spaced by an interval of 6 from the appearance of pulse 18 at the input tap 14. The computer operates on numbers of radix 2 so that when a pulse as at 18 of three units amplitude is applied at the input it is required to pass a single pulse to the output and a unity amplitude pulse to the input but delayed to occur in the next pulse period representing the next higher order or power in the input pulse train. The curbed pulse 19 is applied to a limiter stage 21 which is biased to conduct only if the input pulse applied to it is of positive polarity and of at least double unity amplitude so that a single negative unity amplitude pulse is applied back to the input tap 14 with a delay of #. The curbed pulse 19 is also applied to a limiter 27 which is biased to pass only positive pulses of at least double unity amplitude when a double amplitude negative pulse 32 is produced in its anode circuit which is subtracted from pulse 19 to produce a pulse 36. This is applied to a limiter stage 37 which passes only the positive pulse component as a negative pulse of unity amplitude 40 at the output 39. The delay line 11 thus serves both as a unit of the carry-over operator and also to convert the input pulses into a train of curbed pulses thus obviating errors in the computer due to loss of the D.C. component in the input pulse train. Fig. 5 shows a looped storage system in which input pulses applied at 52 are circulated in the loop comprising the delay line 11 which also produces from the input pulses A the curbed pulses B, C. The stage 50 which is gated on the suppressor grid by positive clock pulses applied at 54 is biased so that it only passes pulses of at least unity amplitude. In modifications, (Figs. 7 and 8, not shown), two delay lines are employed in combined carry-over operator and looped storage systems. Specification 716,172 is referred to.
